Introduction
The StarTech.com USB 2.0 extender over Cat5 or Cat6 offers a
simple USB extension, allowing you to place four USB 2.0 devices
up to 100m/330ft away from the computer, which is more than 20
times longer than the normal USB cable length restrictions. The USB
extender is comprised of both the Local and Remote units, which
can be connected together using standard UTP Cat5, Cat5e, or Cat6
Ethernet cabling. Supporting full Hi-Speed USB 2.0 data transfer
speeds up to 480Mbps, the extender is also backward compatible with
USB 1.0/1.1 (1.1Mbps/12Mbps respectively).

Driver Installation
The USB Extender itself does not require a driver installation for
any operating system that supports USB. The USB Extender is a
pass-through hub, so is only seen as a standard Generic USB hub.
Drivers will still be required for any USB peripherals connected to the
extenders.
NOTE: A additional level of USB hubs can be used on the USB
extender (one hub per port), to provide additional USB ports. An
externally powered USB hub is recommended.

Wiring Diagram
The USB Extender uses all four pairs of wires in the UTP cable, so
either T568A or T568B termination can be used. Both ends of the
cable must use the same termination.
